PIPING STRESS ANALYSIS
Support and Solutions in Flexibility Calculation
Our Tasks ?
Well ahead of the site itself, these studies, in particular the flexibility calculations, are essential to assess the environmental and technical constraints and predict the behavior and integrity of the pipes and equipment over the long term.
We carry out the flexibility calculations of your piping and pipelines with the layouts (routing) to check their behavior according to the construction codes CODETI, ASME B31.3, ISO 14692: descents of loads on anchoring and support, weight, expansion, mechanical constraints , leakage criteria…
So many parameters that are taken into account to achieve a stable pipe structure.
These flexibility calculations are carried out with the CAESAR II® software which makes it possible to precisely analyze the stresses and flexibility of pipes subjected to a wide variety of loads, taking into account weight, pressure, thermal and seismic conditions. and other static and dynamic conditions, for both Offshore and Onshore installations, based on user-defined variables and recognized industry guidelines.
Why use our services ?
A pipe stress analysis (thermal flexibility analysis) predicts stresses in piping and loads on equipment resulting from thermal gradients, thermal transients, weights, pressure, and bolt-up strain. This study is typically required for piping that experiences high temperature fluctuations, or for long pipe runs such as hot piping to coolers or headers. Cases where equipment is sensitive to external loads may also require a pipe stress analysis. The study methodology becomes more complicated for piping systems in vibratory service. As discussed below, the design must address conflicting requirements between the pipe stress analysis (where flexibility is desired) versus the mechanical vibration analysis (which requires stiff supports). Methods are available to manage this conflict and create an optimal piping design.
